Bad guy Kaspar was a shocker, but too convenient. Too simplistic to say ""Oh, oh, I had an evil twin!! But I still love you/want you!"" Didn't ring true, cause if he had why wasn't Kaspar tracking Thomas using the dark energy that he instilled into Thomas?
I could see where Eddie's constant rudeness was coming from, due to the brief flashbacks to Eddie's childhood. Eddie's rudeness was because he was being defensive about his true nature: being gay. However, Ms. Folsom undid it all in the end of the book with Nina's comment about Eddie not setting off her Gaydar. With how vehemently Eddie was against being gay, I got the feeling that the author was almost homophobic herself. It soured the book for me.
The insta-love between Eddie and Thomas also didn't ring true, at least from Eddie. It was like he had almost no crisis of self because of the army of bad vampires pushing it aside from their antics. I wanted more build up on that relationship on Eddie's part than what was there.
All that being said, I did whip through it quickly, and it winds up being a 2.5 star read for me that I'm rounding up to 3 stars. Since there is so few books remaining in the series, I'll finish it out, but I don't expect to re-read them.
